ACTUATOR ROTATION

Factory setting for rotation is clockwise.

1. Determine and verify the rotation of the mixing

valve. (The  at portion at the end of the shaft of the

valve is an indicator re ecting the location of the inter-

nals of the valve.)

Acceptable installation orientation for VM-GIB

actuator.

2. Depending on the piping arrangement and require-

ments, rotate the valve to a fully clockwise or counter-

clockwise position.

3. If the valve rotates clockwise-to-open or coun-

terclockwise-to-open, the actuator will require proper

alignment.

4. Remove the Shaft adapter locking pin from the

actuator and position the Shaft adapter onto the align-

ment mark on the actuator. Depending on the rotation

to open, position the Self centering shaft adapter.

a. Clockwise-to-open

Place the shaft adapter right next to the alignment

mark keeping the mark visible.

b. Counterclockwise-to-open

Place the shaft adapter right next to the alignment

mark keeping the mark visible

ORIENTATION

MECHANICAL RANGE ADJUSTMENT

6. Insert the stem extender to the valve and tighten

the extender with an Allen key.

7. Loosely pre-assemble the nuts for the M8 x 2.5”

bolts through the Mounting Plate.

8. Align the bolts to the face plate holes on the valve

body and tighten the bolts.

9. Tighten the nuts to the Mounting Plate.

9b. For 5” and 6” valve bodies use the M8 coupler and

bolt (j & k) in the assembly of the Mounting Plate.

MOUNTING OF ACTUATOR

10. Loosely assembly the 3/16” bolt to the mounting

plate.

11. Slide the actuator onto the shaft and at the same

time insert the 3/16” bolt head into the bottom slot of

the actuator.

12. Tighten the Shaft adapter onto the extender with

a 10mm or 13/32” socket and then tighten the 3/16”

nut. As the shaft and nut is tightened make sure the

actuator stays parallel to the faceplate of the mixing

valve.

Final Assembly

MANUAL OVERRIDE

To rotate the actuator without power present, perform

the following steps:

1) Hold down the PUSH

button.

2) With an adjustable

wrench grasp either the

stem extender or self-

center shaft adapter to

manually rotate the valve.

3) Release the PUSH

button.

Note: If there is no load, the actuator will hold the

new position. If load conditions exist, the actuator will

rotate.

Once power is restored, the actuator returns to auto-

matic control.

The angular rotation is adjustable between 0° and

90° at 5° intervals. With no power to the actuator, the

adjustment of rotation is done by:

1) Remove the actuator

from the valve.

2) Remove the shaft locking

clip and adapter from the

actuator.

3) Return the actuator gear

train to the “0” position by

following the clockwise or

counterclockwise shaft rotation steps below.

MECHANICAL RANGE ADJUSTMENT, cont’d

Clockwise-to-open

a. Insert the shaft adapter to the right as close as

possible to the raised stop.

b. Hold down the PUSH button and rotate the shaft

adapter to the left until it stops.

c. Release the PUSH button

d. If the shaft adapter is not resting against the

left raised stop, remove the adapter and insert it

against the left stop.

e. Place the position indicator to “0” on the outside

scale.

Counterclockwise-to-open

a. Insert the shaft adapter to the left as close as pos-

sible to the raised stop.

b. Hold down the PUSH button and rotate the shaft

adapter to the right until it stops

c. Release the PUSH button.

d. If the shaft adapter is not resting against the right

raised stop, remove the adapter and insert it

against the right stop.

e. Place the position indicator to “0” on the inside

scale.

4. Determine the angle of rotation for the valve’s rota-

tion. Subtract the angle of rotation from 90°.

5. Remove the shaft adapter and insert it with the posi-

tion indicator pointing to mark on the scale calculated

in the previous step

6. Attach the clip.

7. Manually rotate the valve stem to its ‘0’ position

8. Return the actuator to the stem extender and

tighten the shaft adapter to the extender.

WIRING

• All wiring must conform to NEC and local codes

and regulations

• Use earth ground isolating step down Class 2

transformers. Do not use auto transformers.

• The maximum rating for a Class 2 step-down

transformer is 100VA. It is recommended that

no more than 10 actuators are powered by one

100VA transformer.

CAUTION

Do not parallel wire GIB actuators with any other type

of actuator.

Direction of Actuator Rotation

If the actuator turns counterclockwise to open, reverse

the 6 & 7 wires at the controller
